Bus Service 298 provides residents at Tampines Avenue 4, Street 82, Avenue 3 and Street 86 with greater connectivity to Tampines MRT Station and Tampines Concourse Bus Interchange, along with other amenities in the neighbourhood. The new route also benefits Tampines Polyclinic, Our Tampines Hub, St. Hilda’s Primary and Secondary School, Tampines West CC and Springfield Secondary School. This was the eleventh feeder service to be introduced under the Bus Service Enhancement Programme (BSEP).

The route connects with the transport node of Tampines where further bus connections are also offered from the nearby Tampines Bus Interchange. The service continues the 29x series of route numbering used for Tampines feeder routes. It is the second feeder bus route at Tampines after Feeder 292, and the first feeder route to operate out of Tampines Concourse.
